Poor WiFi reception after dropping Google Pixel

[marmeak7]

I had recently dropped my Google Pixel and had to replace the screen because it was completely unusable. Today I got the device fixed but the WiFi signal of the device has gotten radically low. It only shows two bars of signal when I place the device directly on top of the router and fails to connect to the network even then. I found some threads indicating such problem in iFixit.com but no one had given solid answer on that.
Anyone here can help me with fixing this wifi connection issues?

You might have damaged the network receivers. Send it to google for service.

Same problem. No access to google service center.

Hi, I got the same problem here. Unfortunately, Google service center is not available in the country that I live.
I am planning on replacing the daughter board where the Qualcomm Antenna Impedance Matching lies.
Do you think it's a good idea?

Where exactly is the wifi antenna?

wifi - sometimes working, most times not

Hi
i just bought a used pixel with known wifi limitation (seller saif "not allways working"). when i received it, wifi worked a bit, connection was pretty low, but would be enough if it was stable. but it wasn´t...

p did not change anything to the bad connection, so i removed it, unlocked the phone went back to 7.1 Feb. 2016. -> no wifi, tried 8.x again -> nothing, upgraded again to p, still nothing. thought about selling the device.

then, after reading a lot and several beers, the device found many networks and connected itsself when i pressed the back in the upper area (area next to power button, but i am not sure if left or right) by hand pretty hard.

i successfully tried another method, that works: knock it hard on rubber-protected metalchair. -> wifi works.

putting it in the fridge for an hour did not help anything. i had some success with temperature-things on an acer tablet, so i tried this

my question: what is broken? wifi-cable oder wifi chip?

is it possible to detect this without opening? it seems to be a **** to remove this devices display

thanks for any useful tip
